A system for modulating audio effects of speakers is provided. The system includes a selecting module, a playing module, a recording module, a time delay computing module and a modulating module. Based on these modules, the system is capable of determining a time difference and a pitch for each of the speakers, and modulating the time difference and the pitch for each of the speakers to a desired time difference and a desired pitch, so as to ensure that simultaneous sounds from each speaker arrive at a microphone at about the same time and with the same audio pitch. A related method is also provided.

A light guide device () and a backlight module using the same. The light guide device includes: an incident surface (); an emitting surface () adjacent to the incident surface; a reflecting surface () opposited to the emitting surface; a plurality of first V-shaped structures () formed on the emitting surface; and a plurality of second V-shaped structures () formed on the reflecting surface and perpendicular to the first V-shaped structures, wherein respective heigths of the second V-shaped structures increase with increasing distance from the incident surface and respective distances between adjacent second V-shaped structures decrease with increasing distance from the incident surface. The light guide device of the present invention does not need optical elements, and thus has a simple structure. A backlight module using the same light guide plate is also provided.
